Lutz Well, first of all the ADF4351 is a sythesizer to just output a waveform from 35-4400 MHz. Therefore, the term "sensitivity" does not apply. The data sheet lists a value of -80dB for spurious contamination of the output signal. For sensitivity you have to look at the front end, the mixer and finally the log-detector. So, I do not understand your question.

Lutz Well, you have to ask Banggood or research on Aliexpress. I have no idea...

Lutz I have used this programmer successfully on some ESP boards. The pinout on mine was marked with the silk screen.

Q: is this an amp for tx or rx?

Asked by larrykabo on 2021-05-13 10:27:51

Lutz Idon't think its meant to drive an antenna, its not a power amp. But then again, its a useful 100x wideband amp for numerous applications. You may want to consider the noise figure though which is not the greatest, but still ...

Lutz AboutCW, above statement is completely wrong! CW means "Continuous (light) Wave" hence if you apply dc current of 350 mA and have a proper heat sink to dissipate the about 0.75W, then the manufacturer spec sheet guarantees a 0.3W light output. Typically, the efficiency is about 50%. Pulse laser diodes are a completely different story, and indeed they need to be pulsed but with currents in the order of several 10 amps.

Lutz This product has a questionable electronic design. It uses a micro controller which gets confused every time the motor turns on and the batteries are midway in their use. When the batteries are full, this is not a problem but with increased usage the ESR of the battery rises and so does the voltage drop on the MCU below 5V. In that case the motor runs a long time wasting a lot of soap. A simple change in design could help this issue. Maybe worth to report to the manufacturer by Banggood...

Lutz Well the "blip" is there when input frequency matches the LO because it is directly mixed and the log detector wont work at very low (or even zero) frequencies. This simple design does not really resemble a spectrum analyzer. Normally it should be mixed to a narrow band IF that is being detected. Then there would be no blip...

Q: Are TS100 tips compatible with the TS80?

Asked by Lutz on 2018-08-14 04:15:02

Meerweten No, you can see this in the youtube reviews from EEVBlog.

Q: can it burn paper or tape

Asked by aaryav2957 on 2018-05-26 08:18:58

Lutz Yes, but you need collimation optics.

Q: What is polarity?

Asked by mario on 2019-08-19 10:30:11

Lutz DearMario, you find the polarity in the data sheet at: www.frlaserco.com/download/20150610160047/FARL-300M-808-TO56.pdf. The anode ( ) is the middle pin and the cathode (-) is pin 1 to the right when pin 2 (middle) is below pin 1 and 3. This seems a general use pumping laser diode. Be careful it can not tolerate reverse voltages of 2V or greater! Hope this helps Lutz
